This is not necessarily sparc-specific, but I'm running Linux on my |
2 |
Ultra10, so I figure it can't hurt... |

If you run RAID-1, where one of the members of a mirror is running at |
5 |
ATA-33, and the other member is running at UDMA-100, what type of |
6 |
performance can you expect? |
7 |
|

I know that when you write, you'll write to both, which means you still |
9 |
have to write at UDMA-100 and ATA-33 speeds, but when you read, what |
10 |
happens? Is the driver smart enough to read from the faster drive? |
11 |
Does it probe both, and whichever one responds first gets it? |
12 |
|
13 |
Obviously, it would be best to run them both at the same (and highest) |
14 |
speed, but you're limited in the number of drives that can fit inside |
15 |
the case of the Ultra10. I'm considering booting off of the internal |
16 |
IDE, and running the rest of the system off drives connected to a |
17 |
higher-speed PCI-IDE card. The problem is, I haven't found an easy way |
18 |
to put 3 hard disks inside (I just can't seem to get a drive to fit |
19 |
above the floppy...), unless I get rid of the CDROM drive. |
20 |
|
21 |
I've considered SCSI, but the drives are just too expensive, and the |
22 |
higher-end IDE drives out these days are pretty fast. |

Thanks in advance... |
